MODE 0F ARRANGING THE FLU'ES AND GOVERNING THE DRAFT IN COOKING-STOVES.

Specification of Letters Patent No. 1,646, dated June 20, 1840.

To all whom it may concern Be it known that I, CHARLES GUILD, of the city of Cincinnati, in the State of Ohio, have invented certain Improvements in the Manner of Constructing Stoves for Cooking; and I do hereby declare that the following is a full and exact description thereof.

Figure 1, in the accompanying drawing,

' consists in the manner in which I have arranged the flues, and the dampers for governing and directing the draft around the oven, and under the boilers.

In Fig. 1, A, is the top plate of the fire chambers, which I divide into two compartments by means of a movable division plate B, extending from front to back, which is shown in Fig. 2, also, as broken off, at B,.

and more distinctly in Fig. 3. When the division plate B, is removed, a single fire chamber is thereby obtained. At the rear end of the division plate B, there is a partition in form of a V, as shown at G, C, Fig. 3, at the ends of which are two openings, which may be closed at pleasure, by means of the sliding valves, or shutters D, D, thus governing the communication between the fire chamber, or chambers, and the escape flue. The ovens E, E, are immediately under the plate F, F, forming the bottom of the fire chamber; a partition plate G, extending from front to back divides the oven space into two; a falling door H, on each side of the stove incloses these ovens.

The flues which surround the ovens are constructed in the following manner: There is a flue space extendin the whole width of the stove, at the back of, under, and in front of the oven, as at I, I, I, Fig. 2; and this space I divide into four flues, by partitlons extending from the outer plates of the stove to the oven plates. The center partition is shown at J, and this extends down from a level with the plate K, forming the valve seat, passes under the oven, and up the front flue space, to the under side of the plate F, F, forming a perfect partition around these three sides. L, L, are the upper edges of two other partition plates, which, in like manner, extend down the flue space at the back o f, and under the oven, and up in front to the height of a few inches above the lower oven plate, as shown at M, M, Fig. 4:; the front flue is thus actually divided into two distinct spaces only, by the middle partition J, leaving two heated air chambers N, N, in front of each of the ovens. The

two openings 0, O', forming the upper ends of the two'lateral flues, are furnished with two sliding valves, or shutters, P, P, by means of which either or both, of those openings may be closed at pleasure. For .the purpose of throwing the flame and heat of the burning fire more directly up against the boilers, or other cooking utensils, I make an offset or rise in the plate F, as at F, which thus contracts the flue space leading to the escape pipe or flue Q. The sunk hearth, with its sliding cover, and other devices which are in ordinary use, although shown in the drawing, it is not necessary to describe.

R, is a sliding shutter, closing an opening for cleaning out the lower flues, a similar shutter being removed, and showing the partition M, Fig. 1. 7

By means of the foregoing arrangement of the valves, flues, fire chamber, and ovens, I am enabled to use one half only of my stove at any time, and to direct and govern the heat as I may think proper; or when the whole is used I can regulate the heat of the two ovens, so that one of them may be more highly heated than the other. A very important result of this arrangement is the rendering the temperature of the front plate of the oven nearly or quite equal to that of the back plate, it having been found, in practice, that the spaces N, N, forming a part of the front flues, where the direction of the current of heated air is changed, operate as reservoirs of heat, and produce this desirable result.

Having thus fully described the manner in which I construct and arrange the respective parts of my stove, what I claim therein, as constituting my invention and improvement, is

The manner in which I have combined and arranged the three partitions dividing the flue space into four compartments, ex- I do not claim either cfthese parts sepacepting at the front, Where the-two lateral rately or individually, but only in combinapart-itions terminate, in the manner, and tionas'abeve. for the purpose set forth; and I' also claim, 3,

in combination with thepartitions s0 ar- Witnesses: ranged the employment of the dampers D, EBENEZER HARRISON, and P, operating substantially as described. SAMUEL W. CQSWIN;
